FLEXIBLE SHAFTING.

Application filed June 29, 1926. Serial No. 119,346.

The present invention relates to flexible shafting particularly,although not necessarily, adapted for use with motor boats for drivingthe propeller.

The principal object of the invention is to provide a flexible shaftingwhich will operate efficiently and in a reliable manner under theconditions found in driving the propeller of a motor boat.

Another very important object of the invention is to provide a flexibleshafting which will prove strong and durable in use, one which iscomparatively inexpensive to manufacture, not likely to easily becomeout of order, and otherwise well adapted to the purpose for which it isdesigned.

lVith the above and numerous other objects in View as will appear as thedescription proceeds, the invention resides in certain novel features ofconstruction, and in the combination and arrangement of parts as will behereinafter more fully described and claimed.

In the drawing Fig. 1 is an elevation of one embodiment of theinvention, and

Fig. 2 is an end elevation thereof.

Each section of the shaft is formed with a cylindrical body 21 havingconical ends 22, through the apices of which project eyes 23 and fromthe base of which project arcuate elongated loops 24. The eyes 23 andthe loops 24.- of each section are interlinked with the respective partsof the other sections as is clearly shown in Fig. 1. It will thus beseen that these loops 24 take the strain off the eyes 23 at all times,during the rotation of the shaft.

It is thought that the construction, operation, and advantages of thisinvention will now be apparent by those skilled in this art without amore detailed description thereof. The present embodiment of theinvention has been described and shown in detail merely by way ofexample, since in actual practice it attains the features of advantageenumerated as desirable in the statement of the invention and the abovedescription.

Numerous changes in the details of construction, and in the combinationand arrangement of parts may be resorted to without departing from thespirit or scope of the invention as hereinafter claimed or sacrificingan of its advantages.

Having thus described my invention, what I claim as new is A flexibleshafting of the class described including a plurality of sections, eachsection including a body having outwardly projecting conical-shapedends, eyes at the apices of said ends, a series of arcuate elongatedloops at the base of each end, the loops and the eyes of the sectionsbeing interlinked for connecting the sections together.

In testimony whereof I afl ix my signature.

JOHN T. DUNN.
